    Comments about Tuta Mail as an Alternative to Proton Mail
    Comment summary: Tutanota is praised for its affordability and transparency, offering end-to-end encryption and a generous free storage plan that appeals to budget-conscious users. However, users note a wait period for account activation. It is considered user-friendly, though Proton Mail is seen as more secure but pricier. Tutanota encrypts titles and contacts, which some believe gives it an edge in privacy. Overall, it functions well on secure browsers and maintains a straightforward encryption model.

    Tutanota is end-to-end encrypted, as well offers 1 GB mail storage on free plan. The pro plans are cheap compared to protonmail, so it's better for low budget users

    Tutanota has historically been a lot more transparent, and arguably has been more honest about issues and plans

    I use both, ProtonMail is more secure but also more expensive and not as user-friendly. You cannot beat the price of Tutanota for service they provide.

    Proton is not confidential at all, because it is under the influence of the EU. The best thing you can find for anonymous messaging and file sharing is the Utopia ecosystem (U.IS)

    Mailfence offers more functionality than Proton mail with Calendar, Document, Chat, and Group functionality. Moreover, the price is much lower than other competitors.

    Vivaldi mail offers PGP-based email encryption, similar to Protonmail. But the web client is much less well developed. However, unlike Protonmail (at the time of writing), they allow you to import your own PGP keys, which is nice (a feature Protonmail users have been demanding for years).

    Even thought Proton Mail is a good privacy focused email, it still holds both your emails and your keys on their servers. Regarding ownership, Criptext gives the user ownership over their keys, which reside only on the user's devices. It also uses Signal Protocol for encryption which I personally like better than just using pgp.
